Yes, I'd also be happy about changes to the docs, let's really not encourage new uses of foreach. But I think we'd do ourselves and especially our users a disfavor by deprecating it. I have seen enough bugs introduced by people fixing deprecation warnings blindly, and there seem to be so many issues when it comes to foreach that I think it's simply not worth it.
